feat!: replace `lazy_static` with `once_cell` (#69)

Extended commitment generators are currently
[produced](https://github.com/tari-project/bulletproofs-plus/blob/502ae9fa3/src/ristretto.rs#L154-L179)
using the `lazy_static` macro. Unfortunately, `lazy_static` is [no
longer actively maintained](https://crates.io/crates/lazy_static). Other
repositories in the ecosystem are moving to `once_cell`, which is
[actively maintained](https://crates.io/crates/once_cell).

This PR migrates from `lazy_static` to `once_cell`. In the process, it
cleans up the construction. Specifically, it moves from using word-based
numbering (_e.g._ `ONE`, `TWO`) in hash inputs to numerals, which
simplifies the design. It also adds a useful test that asserts the
number of generators matches the size of `ExtensionDegree` to avoid
panics.

Closes #67.

BREAKING CHANGE: Modifies the construction of commitment generators.
